Tune in Today: “Duck Dynasty”

“Duck Dynasty” (9 p.m., A&E, TV-PG) celebrates the season with “I'm Dreaming of a Redneck Christmas.” For the uninitiated, this popular cable series follows the antics of the Robertson family. Their patented duck call has made them quite wealthy, but the backwoods vibes pervades. In many ways, it's a reality sitcom.

Viewers seem to love this stuff. From rustic exterminators to swamp dwellers and “Moonshiners” (7 p.m.-10 p.m., Discovery), these shows attract audiences that often top the cable charts. According to A&E, more than 4.9 million viewers watched “Duck Dynasty” last week. “American Horror Story,” the second-most popular cable series last Wednesday, had half that number.

Maroon 5 and Dierks Bentley are among the scheduled performers on “The Grammy Nominations Concert Live!” (9 p.m., KENS). The Grammys air next February.
